Black polyurethane foam adhere rocks to pond liners so you can create stunning waterfalls like a pro for a fraction of the cost. Handi-Foam Polyurethane Foam Sealants dry tack-free in less than 10 minutes and typically cures within one hour. Fire-rated OK for electrical. Handi-Foam Polyurethane Foam Sealants are available in a variety of sizes to meet many pond application needs. Foam color may lighten as it dries.

Use multipurpose Polyurethane Handi-Cleaner spray solvent to dissolve excess uncured foam and adhesive for easy cleanup. Handi-Cleaner can also be attached to Steel Handi-Gun foam sealant dispensing unit to flush and clean unit (Handi-Cleaner is not for use with the Polymer Handi-Gun).

Fomo Products Handi Foam Polyurethane Foam Sealants

Handi Foam Polyurethane Black Foam Sealants are one component polyurethane foam (OCF) sealants specifically designed black in color, making it ideal for applications where product appearance may be a factor. Handi-Foam Black Sealant utilizes a (HC) propellant.

Handi-Foam Black Foam Sealant is available as a 12 oz straw foam and a 29 oz gun foam. The gun foam version is designed to be dispensed through any Handi-Tool dispensing unit. The Straw Foam version is designed to be dispensed through a straw adapter (included with each can).

Application Areas
Handi Foam Polyurethane Black Foam Sealant may be used to fill gaps and cracks in pond and waterfall design, landscaping, RV undercarriages, crack and hole repair in trees as well as to seal gaps and penetrations in the building envelope. Handi Foam Polyurethane Black Foam Sealant is fish and plant safe.

Properties
The pre-pressurized, portable OCF system, applied in a bead form, expands and cures slowly to a semi-rigid, closed cell foam upon reaction with moistures such as ambient humidity.

Handi Foam Polyurethane Black Foam Sealant dries tack-free in approximately 5 minutes or less depending on moisture and temperature conditions. The foam fully cures within 24 hours. Expansion of 2-3 times the dispensed bead within the first hour should be expected. It is recommended to fill the cavity only 1/3 of the way full to allow for expansion. Handi Foam Polyurethane Black Foam Sealant will adhere to itself if more foam is applied.

Handi Foam Polyurethane Black Foam Sealant adheres to almost all building materials with the exception of surface such as polyethylene, Teflon® silicone, oils, greases, mold release agents, and similar materials.

Optimum chemical temperature is between 65°F and 80°F, but may be applied in cold or hot ambient conditions, as long as the optimal chemical temperature range is maintained. Cured foam is dimensionally stable, and known to be resistant to temperatures ranging between -200°F to +240°F.

Handi Foam Polyurethane Black Foam Sealant is water resistant and will not harm electrical wire insulations, Romex, rubber, PVC, polyethylene, or other plastic (i.e. PEX, CPVC). It is approved for use around wires, plumbing penetrations, etc. When cured, polyethylene foam is permanent, nontoxic, chemically inert, nonreactive and stable for an indefinite period of time. Cured foam should be protected against UV rays (i.e. sunlight) by painting or staining to prevent long term discoloration or degradation.

Application/Use
After following instructions for setup, the cans are ready for use.

Straw Foam Option: Attach the straw, shake well, invert the can, and begin dispensing. By activating the adapter lever carefully, the extrusion rate can be regulated.

Gun Foam Option: Attach the can to the dispensing unit (Handi-Tool Gun), shake well and begin dispensing. The dispensing units can be metered by pulling the dispensing unit trigger for the desired rate, or with the metering screw located in the back. Foam application can be interrupted when needed as outlined in the instructions and the dispensing unit will be ready for immediate reuse, as long as it remains attached to a pressurized container. An empty gun foam container must be replaced with a new container.

Handi Foam Polyurethane Black Foam Sealant is especially useful for irregular voids and on non-linear cracks and crevices. Filling excessively large cavities can result in prolonged curing process. Also insufficient air or substrate moisture during curing may cause delayed expansion.

Remove fresh foam over spray with Polyurethane Handi-Cleaner or solvents such as acetone. Cured foam can only be removed mechanically.

Special Handling
The propellant is extremely flammable during dispensing and curing. Provide sufficient cross-ventilation to remove any buildup of vapors. Keep away from heat, sparks and sources of ignition. Turn off all pilot lights. Vapors may cause flash fire if ignited. Contents are under pressure. Do not puncture, incinerate or store above 120°F. Do not place in hot water or near radiators, stoves, motor vehicles or other sources of heat. Cure urethane foam produced from these ingredients will support combustion and may present a fire hazard if exposed to a fire or excessive heat +240°F.

The nitrification process, or the nitrogen cycle, plays a crucial role in creating a healthy pond. This natural process converts toxic nitrogen waste products into less harmful compounds. Discover how you can maintain efficient biological filtration.

Did a lot of research to see who had the biggist bang for the buck, it surly was rt here, twice l hav ordered this product from this site in a months time, my waterfalls in my 3 ad-joining ponds are awesome using this product,

Works very well!
I used this on my 215 gallon aquarium all along the back (to ad texture and to make it look better). If you have every used "Great Stuff" on your household projects then this will be very familiar. LAY IT DOWN SLOWLY OR IT WILL RUN! It also would help having the tank on it's side instead of trying to lay it vertically. Work from the bottom up. This is a great project (I just hope they were correct about it being non toxic). I JUST BOUGHT 5 MORE CANS! This works very well.
